“…The pyrolysis temperature and maximum heating rate decreased and conversion rate increased obviously after copyrolysis. The pore size and acid sites of the Ni particles affect the devolatilization and gasification processes, which weaken the C─C, C─H bond and enhance the conversion of biomass, thereby increasing the complexity of the pyrolysis process and the pyrolysis mechanism. Above data analysis implied that metal impregnation modification facilitates thermal decomposition because of changes in the hydrogen bond structure, which can effectively shift the thermal degradation temperature to a lower temperature, increase the conversion rate and thermal decomposition speed.…”

“…The number of internal rotation degrees of freedom is converted to the degree of freedom of vibration, and thus, the pre‐exponential factor is reduced . The values of enthalpy and entropy are different under the action of different metal salts, which is consistent with the Ea, which was due to the energy difference between the reagent and the complex activated species . The positive Δ H values suggests that higher enthalpy values indicated a less reactive system .…”

“…Also, Ni catalysts exhibit their effect in C─H and C─C activation, Fe has a positive effect on C─H bond activation and Co is the most beneficial to C─H and C─O bonds. Therefore, according to changes in the energy distribution, the thermal decomposition temperature shifts to the lower temperature. Moreover, because of the high acidity of Ni, the effect of deoxidization is better and the conversion of modified cellulose is promoted; therefore, the content of coke is lower.…”

The present work aims to investigate the thermal behavior, kinetics, thermodynamics, and product distribution during copyrolysis of transition metal salt (Ni, Co, Zn, Cu, and Fe)-added biomass and model compounds with low density polyethylene(LDPE) over a Ni-based HZSM-5 catalyst by TGA and fixed bed reactor. The interactions and reaction mechanisms during copyrolysis were evaluated. The influence of Ni-impregnated biomass (C-M) and Nimodified HZSM-5 (Ni/HZ) on the formation of pyrolysis bio-oil from biomass and model compounds and its subsequent effect on catalytic pyrolysis vapor upgrading was discussed. The results indicated that the presence of transition metal decreased the thermal degradation temperature and thermodynamics parameters; maximum decomposition rate, and reaction complexity. Ni/HZ catalyst could further decrease the activation energy, accelerate the reaction rate and change reaction process, and the modified samples/LDPE under copyrolysis with HZSM-5 catalyst presented a more significant effect than Ni/HZ catalyst. Subsequently, the Ea of pine, cellulose and lignin changed from 24.11, 18.29, and 28.68 kJ/mol (CP@Ni/HZ) to 56.04, 69.84, and 16.21 kJ/mol (CP-Ni@HZSM-5), respectively. In addition, Ni could inhibit the depolymerization of cellulose and promoted the formation of char, coke, and lignin derived phenolics. And Ni-impregnated biomass reduced the formation of desired aromatic hydrocarbons, but result in increasing of the char and non-condensable gases. But Ni/HZ catalysts promote the conversion of biomass to target products.

“…The higher sum of fixed carbon and volatiles indicated the fuel had a better ignition performance [7]. The sum of volatile matter and fixed carbon of the PSH (84.98%) was higher than water hyacinth (72.65%) [9], indicating a better ignition performance of the PSH. Determining whether more oxygen-containing functional groups are included in volatile organic compounds can be derived from high O/C and low H/O [30].…”

The influences of four heating rates on the combustion and pyrolysis behavior in the N2 and air atmosphere were investigated by the Fourier transform infrared spectrometry (FTIR) and thermogravimetric (TG) analysis. the distributed activation energy model (DEAM) and Flynn-Wall-Ozawa (FWO) were used to estimate Ea and A, ΔH, ΔG and ΔS. Experimental results showed that the similar thermal behavior emerged, but the temperatures in the air and N2 atmospheres representing the end of the reaction were about 500 °C and 550 °C, respectively. The results of FTIR showed the peak positions were basically the same, but the concentrations of aromatics, aldehydes and ketones produced by pyrolysis in the N2 atmosphere were higher. When the heating rate was 20 K/min, the comprehensive combustion parameters were 56.442 and 6.871 × 10−7%2/(min2• K3) in the air and N2 atmospheres, respectively, indicating that the peanut shells had great potential to become bioenergy.

Aquatic plants have been considered as a cause for concern because they impede aquatic flora and fauna. However, biofuel production from aquatic plants is an emerging energy source. As a consequence, this paper presents a detailed review of bio‐fuel production from floating aquatic plants with their physicochemical properties. The main focus of this study is to evaluate the biofuel production potential of some major aquatic plants. This paper also presents some methods for biofuel production from aquatic plants that are feasible for future energy generation. Five major types of floating aquatic plants are analyzed in this study, viz. Azolla, water hyacinth, water fern, water lettuce, and duckweed, with their related biofuel production methodologies such as transesterification, pyrolysis, hydrolysis, and torrefaction. This paper also evaluates optimum bio‐fuel production conditions for aquatic plants and their upgradation methodologies. Conventional fuel and aquatic bio‐fuel properties are also compared in this study. Findings suggest that, depending on calorific value and viscosity, Azolla and water fern (Salvania molesta) are better aquatic plants to generate high‐quality (similar to diesel) biofuels compared with other aquatic plants. Bio‐fuel production from water fern, water lettuce, and duckweed are also comparatively less focused sources of energy. The cost associated with cleaning invasive aquatic plants from water can be turned into an investment by producing biofuel from aquatic plants using sustainable techniques. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
